Pressing mechanism for molding APG (automatic pressure gelation) insulating part

Abstract

The invention discloses a pressing mechanism for molding an APG (automatic pressure gelation) insulating part. A pressure plate is arranged on a rack through a drive device in a reciprocating motion manner, wherein a guide device comprises an X-axis guide mechanism, a Y-axis guide mechanism and a Z-axis guide mechanism, wherein the Z-axis guide mechanism comprises two sliding rail seats and two sliding rails; the two sliding rails are symmetrically fixed on the rack; various sliding rails are arranged on the sliding rail seats in the reciprocating motion manner; one end of each sliding rail is fixedly connected with the pressure plate; the X-axis guide mechanism is arranged between the rack and the sliding rails; and the Y-axis guide mechanism is arranged between the rack and the sliding rails. Through the additional arrangement of the X-axis guide mechanism and the Y-axis guide mechanism between the rack and the sliding rails, limiting in the X-axis direction and the Y-axis direction is realized; yawing force caused by inclination of the overall mechanism in the X-axis direction and the Y-axis direction is removed; swing of the sliding rails in the X-axis direction and the Y-axis direction is avoided; accurate guide of the X-axis guide mechanism and the Y-axis guide mechanism is realized; and processing accuracy is ensured.

Description

technical field [0001] The invention relates to a pressing mechanism for forming an APG insulating part, in particular to a pressing mechanism for ensuring the forming accuracy of the APG insulating part. Background technique [0002] In the manufacturing process of APG (APG: technology is epoxy resin automatic pressure gel molding technology (The Automatic Pressure Gelation), which is mainly used in the production of medium and high voltage epoxy insulation products), one of the processes is to fix the pole Positioned in the mandrel and achieve the purpose of pressing and forming through the pressing structure; wherein the pressing structure includes a frame, a pressing plate and four guide columns, and the pressing plate is connected and linked with the hydraulic cylinder to achieve APG insulation Two guide copper sleeves are installed on each guide column; the above-mentioned press-down structure is inclined, and the weight of the entire press-down mechanism is more than...
